Abstract

Clipping is a very important function in two-dimensional sketches, and users can obtain the desired curve through clipping. This paper mainly studies the clipping problem of the second-order Bezier curve. First, solve the problem of intersection between Bezier curve and line segment, circle, Bezier curve, etc. Then, by traversing the intersection point, determine the intersection point on the two sides closest to the mouse point, and determine whether the cut is the middle section, the start or end section, or the entire curve. Get the clipping algorithm of Bezier curve. Finally, the cutting function was applied to the MTSS simulation software independently developed by the research group, and good results were obtained, which improved the modeling ability of MTSS two-dimensional sketches.
